Definitions
- the invention relates to a mounting for a muzzle member on a gun barrel of the type disclosed in German published Patent DE-PS No. 1230334.
- Such known muzzle member is mounted by means of two separate parts that are threadably mounted, one behind the other, on the free end of the gun barrel and are secured against loosening by rotation.
- An outer frusto-conical portion of one member includes longitudinal slits whereby the muzzle member is threadably mounted via extending portions of the member which are biased against an outer conical surface of the free end of the gun barrel and thereby are spread apart in such a way that they permit a rotation of the muzzle member relative to a rotational locking in the form of at least one pair of spring tongues defining a gap.
- the invention has as an object to provide a mounting for a muzzle brake member of a gun barrel which is improved in such a way that between the muzzle outlet portion and the gun barrel there is provided in addition to an axial fixing and a safety lock against rotation a radially play-free joining due to oscillations of the muzzle outlet portion at firing, which oscillations may occur due to finishing tolerances of the connecting elements.
- This object is advantageously achieved by means of a simple, play-free and rugged type of joining between the outlet portion of the muzzle and the gun barrel.
- the muzzle brake member and gun barrel are joined to each other over relatively long conical surfaces in a play-free manner.
- the conical surfaces and the rotational locking means are further advantageously insulated from exterior forces so that at all times an exchange of the muzzle member is possible. Additional guide means as well as long mounting threads are eliminated by the type of mounting of this invention.
- FIG. 1 the drawing illustrates in longitudinal cross-section the muzzle member of the invention shown as mounted on the free end of a gun barrel;
- FIG. 2 is a partial cross-sectional view of the muzzle member of FIG. 1 showing its elastic deformation.
- a muzzle member 4 constructed as a muzzle brake 4.1, which has a rear line threaded portion 6 and an internal frusto-conical portion 5.
- the gun barrel forward end has, on the other hand, an external threaded portion 3 which mates with the inner threaded portion 6.
- the external threaded portion 3 is disposed behind an external frusto-conical portion 2 of the gun barrel, which constitutes the forward end thereof.
- the gun barrel frusto-conical portion 2 is matingly shaped with respect to the inner frusto-conical portion 5 of the muzzle member 4 so that when the muzzle member 4 is threadably mounted on the external threaded portion 3 via the inner threaded portion 6 there results a rugged, prestressed and thereby durable connection.
- the threaded portions 3, 6, are constructed as fine threads in order to mount and dismount the self-locking conical connection.
- the threaded portions 3, 6 assume only certain predetermined support functions for the muzzle member 4 so that the axial length 1 2 is smaller than the thread diameter d 2 .
- the outer frusto-conical gun barrel portion 2 of the gun barrel 1 includes at least four transverse recesses 8 equally angularly spaced about the periphery of the portion 2 which recesses 8 serve for acting as a rotational safety lock 7.
- the rotational safety lock 7 includes a safety rod 10 which is deposited in cutout 11 when the conical joint is in its safety position, which bore 11 is transverse to the axis 9 and also tangential to the inner frusto-conical portion 5. Thereby, by means of the part 12 of the rod 10, which extends into the space of the inner frusto-conical portion 5 along the flat bottom 13 of the recess 8 there is obtained a locking action.
- the strength and wall thickness S of the inner-frusto-conical portion 5 of the muzzle member 4 is selected in the longitudinal region 1 1 in such a way relative to the angle of inclination ⁇ and the thread angle, that when firmly screwing on the muzzle member 4 by means of known mounting tools (not illustrated) there is effected on the parallel surfaces 14 of the muzzle member 4 a certain elastical enlargement of the muzzle member 4 in the region 1 1 for assuming a locking position in one of the recesses 8 of the lock 7.
- the width b of the bottom 13 of the recess 8 is dimensioned is such a way that, after contacting of the conical surfaces 2, 5 and the resulting further rotation of the muzzle member 4 into the next locked position the rod 10 is slit into the bore 11 which is parallel to the recess 8 for securing the muzzle member 4.
